Overview of Diabetes and thee Need for Rapid- Acting Insulin

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia resutting frem defects in insulin secretion, insulin action, or both. In type 1 diabetes, autoimpete destruction of patiatic beta cells leads to an absolute defectionce of insulin, requiring exogenous therapy for survisval. In type 2 diabetetes, insulin resistance combinad with progressive beta- cell dysfunction of leads thee need for insulin ains the disease advances, some times neatine, some multiple perions perions perions.

Te goale of insulin therapy is mimic thee body 's normal physiological insulin secretion: a low continuous basal level combined with rapid, sharply rising spikes at t mealtimes.

What Is Lyumjev? Mechanism of Action

Lyumjev is a formulation of insulin lispro with added excipiens that akcelerate its absorption after subcutanous injection. The active contrigent, insulin lispro, is a contriminant human insulilin analog where the proline at position B28 andlisine at position B29 are reversed. This structural change reduces the tendencency of contrilin contricuules to form hexamers, promoting rapíd disocisociation into monomers and dimers insertion site.
